Abstract
This study assesses the energy, exergy, economic, and environmental performance of a gas stabilization unit by employing a new strategy to implement an advanced control system. The advanced process control (APC) strategy is established based on the response surface methodology to assess the real-time performance of the process. The RSM-based APC technique targets the energy, exergy, economic, and environmental (4E) performance of the process in unsteady-state operations. A detailed sensitivity analysis is also conducted to evaluate the relative significance of operating parameters on the objective functions, such as exergy efficiency, energy cost, and CO 2 emission. The RSM-based APC strategy proposes an algorithm that can readily be implemented in the plant to increase the plant’s energy performance. Implementing this intelligent control system leads to the production of standard products, while production cost, energy consumption, exergy efficiency, and environmental impacts are enhanced. The exergy and sensitivity results indicate that the stabilization tower has the highest potential for process enhancement, and reboiler temperature is the most influential factor among operating parameters. Also, the RSM-based APC improves the exergy efficiency of the plant by 19% and reduces the energy cost by 13%. At the optimal state, 457 kg/h CO 2 emission is prevented.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
